New Features and Functionality for Previous Upgrade 2.60
The follower winder feature can be likened to an “electronic fishing reel”. With this feature selected,
the slave axis will follow within a specified distance zone and then at the end of the zone, reverse
direction and traverse the distance in reverse. This cycle will repeat indefinitely. The follower axis
will always stay within the zone for both directions of master commands. During the winding motion,
the PLC can send zone adjustments to accommodate winder reel taper on either or both sides of the
Winder Mode Configuration
Follower Winder Mode Enable
: Use the Configuration Modes immediate command to select the
Winder with the desired taper mode. At the same time, the Zone Position Register may be selected
for return in the %AI data if desired. The Configuration Modes immediate command must be sent
only when the Follower is not enabled.
Taper is only applied when the PLC sends a different winder zone length.
Winder Zone Length
: Use the Follower Winder Zone Length immediate command to establish the
initial move zone length for the winder motion. This same command may be sent later during the
winding operation to alter the zone length to produce the desired taper.
Important Product Information
Winder Mode Operation Steps
With Enable follower OFF, set the winder zone length to the count value representing the width
of the spool or the total distance to be traversed in each direction for the winding operation.
Command the follower axis to the winding start point and then send the Set Winder Position
%AQ immediate command to synchronize the axis position to the winder zone and define the
starting position within the zone. The magnitude of this preset value indicates the axis position
orientation within the winder zone. Zone position = 0 corresponds to the extreme left (most
negative) side of the zone and Zone position = + (zone length - 1) corresponds to the extreme
right side of the zone. The sign of the preset value determines the initial direction of movement.
More specifically, when positive master commands are followed, a positive position preset will
cause the winder axis to first move in the positive direction and a negative position preset will
cause the winder axis to start in the negative direction. The reverse of this is true when the
master command is negative.
Set the Enable Follower %Q bit to start the axis winder motion in response to master commands
